Why work is a scaler quantity and torque is a vector quantity. What is the difference between torque and work. Please explain

Work is equivalent to energy spent by us to displace a body.
 
If we do some work on a body its Kinetic energy increases, it means our work is in that body in the form of Kinetic energy. So it is scalar quantity.
 
Torque is the rotational analogue of force. In torque we want to know that to give the rotational effect how much force is needed and where and how that force must be applied.
 
Torque= force displacement sin?

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
